It looks like you’d like to back-test a daily-rebalanced, 500-stock portfolio strategy. At the moment our back-testing engine can evaluate signals on a single ticker at a time (or on a single, pre-defined event list). Because your idea involves building a new basket of 500 stocks every day, we first need to pin down a few practical details and confirm how you’d like to treat the portfolio construction:

1. Universe • Which market(s) should we draw the “top 500” from – e.g. all U.S. common stocks, a specific index membership list, or another set? 2. Ranking logic • Is the selection based on that day’s raw dollar volume, share turnover, or another volume metric? • Should the list be determined at the close and positions opened at the next day’s open (close-to-open implementation), or do you prefer another timing convention? 3. Portfolio weighting • Equal-weight across the 500 names each day, or weight by volume / market-cap / something else? 4. Practical simplifications • Given that our current single-ticker back-test engine doesn’t directly support multi-asset baskets, are you open to an approximate solution – for example, testing the idea on a representative ETF (equal-weight / high-volume) or on a subset of tickers – or would you prefer waiting until we can accommodate a full multi-asset back-test?

Once I have your preference on those points, I’ll set up the data-retrieval plan (and any suitable approximations) and run the back-test for you.
